TO ALL WHOM IT MAY CONCERN:`

-Be it known that I, ROBERT KIRK BOYIQE, of the city, county, and Stateof New York, have invented a new description thereof, whchlwill enabletlise skil ed in the art to make and use the same, reference being hadto the accompanying drawings, forming part of this specification.

This invention relates to a newr telegraphic-printing apparatus, whichis so arranged, lthat it will adapt itself te every variation oftheweather, and that `will utilize the whole power ofthe current' Theinvention consists, first, in a new arrangement of connecting thehorse-shoemagnet with .the electro magnets.4 l v I I In my new apparatusfour electromagnets are employed, apair being arranged on each sideofthe horse- The two electro-magnets oneuch side arearranged one abovethe other. Two horse-shoe magnets areirmly'secured toanoscillating-horizontal bar, in such a'manner that each end of eachhorse-shoe is between the two opposite electro-magnets.

By means of this arrangement the through current, -which is generallyobtaincfhis avoided, and the horseshoe magnet willmore easily change itsposition', when the polarity of the electro-magnet is reversed;

The invention also 4consists in the application of two springs, of whichone is arranged on eachl side ofV the horse-shoe magnets, so as to beforced 'back by the magnet, when the same is attracted to .one side, andto aid in repelling it to the other side, when the current is changed. ll

By means of these springs the motion of the horse-shoe magnet can beregulated, in case the electro-magnets on one'side should be strongerthan those'onthe other side. l i f y' Y By setting the spririwhicli' ison the same side with the stronger coil, by means of a 'set-screw,closer-'to the horseshoe, thus strengthening it, and by weakening thespring on. the weaker coil, the horse-shoe will be repelledwith theadditional force-of the stronger spring, when attracted by the weakerelectro-magnet?- The inventin consists, third, in a new method ofconnecting the horse-shoe magnet with. the Vlocal magnet,

This connection consists of two wires, which reach from the coil of -thelocal magnet tojits lcattery, and thence to a slotted standard, in whichthe horse-shoe oseillates, andto a sleevein which th'e'horseshoe-isheld, respectively, the saidsleeve being held between the two arms ofthe aforesaid standard. i

As soon as,'by the actionupon' the keys, 4the m'otion of the armature-is-arrested, t he sleeve will'be' brought in contact with the standard,andthe circuit between the two wires of the local rmagnet will beestablished, so that the same will draw down its armature. l l 'l Theinvention, vfonrthly, consists in connecting the local magriet with aforked lever, acting'as an escapement to .a toothed whe'cl, which has atendency to revolve, but is detained by the aforesaid lever.

As soonas theI armature ofthe local magnet is drawn down, the wheel willbe released, and willrcvolve until it is'stopped by another forked leverconnected with the type-wheel, as 4will hereinafter be' more fullydescribed. y

By such a mot-ion ofthe wheel; the same will, by m'eans of pins, actuporra lever, which draws a clutch into the Ateeth of a stationary`tlisk, the number of teeth on the same corresponding with thennmber ofletters on the type-wheel. I f l f 'l l j Thetype-whel is mounted onan'airle, which carries an arm that strikes against the'aforesaidclutch,when the same catches into one-ot` the teeth of the aforesaidstationary'clisk, and which thus stops the motion of the axle, to whichit is attachedand consequently also the motion of*the'type-wheel.V Thetype-wheel is thus brought to a stop and-ready for printing. I A

'BLEU The invention alsosconsists impartingto thou-axle, to which thetype-wheelis attached, motion from sloot s, turning upon a stationaryagile, which is a continuation of the aforesaid type-wheel axle.

V'.lfo the 'slccvc'is ivoted anelhow-cam which strikesafaiust a in enthe type-wheel and thereb revolves p 7 o p .l y

f the same as 'the sleeve isrevolvcd.

'Botas soon ase ,he type-wheel isstopped in Vth'c aforesaid rnaniner,the cani will'not be able to movie it any more,l and will, as it isattached' i'ofthe 'revolving sleeve', .beu forced against the `pin onthe type-wheel, and will thereby be turned aroundlitspivot-pin, so thatits other arm will strike against a pin on another sliding sleeve,which, as ift is thusmoved, acts upon a'lever projecting from 'anoscillatngshaft.

As the latter shaft is turned itwill press a cushion which is attachedtoit against the type-wheel', and will thereby imp rcssthe requiredletter upon the paper, which isbetweenti'ic cushion and the type-wheel.i

The invcntion'iilsio consists inconnec'ting with the oscillatingaxle,v'\vhi`ch carries the printing-cushion, the forked'escapement-lever, which arrests the motion of thetoothed wheel, that hasbeen released by the action of the local magnet, as above described.

' When, by the stopping ofthe-typc-wheel, the .said-'forked leverismovcd, it acts to again release the toothed wheel, so that it may belocked by the lever which is connected with the local magnet.

A spring acts to draw the printing-cushion and all the parts connectedwith the. oscillating axle to which it is attochcd'into the originalposition again.

The paper to be printed is fed between two. drums," which are'movcd bythe intermittent rotary motion oi` the toothed wheel that is connectedwiththelocal magnet.

While the aforesaid toothed' wheel'rwas turned, when released from thefork that is connected with the printing-cushion, it acted upon thelever which cai-ries ythe clutch,-itting into the toothed disk, so lasto draw theclutelr eut,`and thereby allow the' typewhcel and its axle torevolve'again.

The invention also consists in the device for connecting'th'eaforesaidapparatus withthe armature of the mainniaghcts.

The oscillating armature operates an oscillating escapement, which actsupon a toothed wheel, mounted on 'aslcevc that is fitted up'on thetype-whcelvaxle.

lThe little toothed wheel has half as many teeth asv there are types,and its sleeve isconhected with the sliding clutch which locks into thetoothed disk. i

As the toothed wheel is released lby theoscillations of its'levcr, andmovedv by theaction of aspring, the clutch-arm will move 4'ith each moveof thc toothed wheel, opposite to another tooth of the toothed disk, and

when the oscillations of the escapeme'nt are stopped, the clutchv willbeopposite that tooth into which itis to vbe-loeked bythe actionot` thelocal mognet.

When the'arm on thetypefwheel shaft strikes the olutcln-th-crequiredtypc et' the wheel' will stand oppas site theprintin'g-cushion;

The correctness of the operation is evident, as each motion of thearmature makes one corresponding motion Vof they toothedeseapoment-whecland one motion of the clutch-arm, which nieves `opposite the tootheddisk, the

disk having as iuiany recesses as there are types.'

Each recess 4represents one type, and that one into which the clutchearmis locked will be the representative' of that type,"which will bebrought opposite to the printing-cushion.'

The inventionl consists also in the device for winding up the spring,which moves the escaperuent-wheel'.

The outer end of this spring is attached to an annular r'atchebivhcel,w'hichis held on tbc side of a stationaryl rin'gpand which iscon'ncctcd'with a suitable pavrl.l it On the samesleeve to whichV theescaperuent-whcel and theinner `end of the spring are attached, is alsoattached an'inclincdicam', upon thel edge of which straddlcs'e. forkedlever, pivoted to an erin that projects fromthe type-wheel shaft. i i pA' i; i

As the shaftl revolves, the fork is moved on the oa'm,`and if the springis unwonnd, it will be wound-,up

again by an arm projecting from the fork, which arm only strikes a blockon lthe spring when it moves over thotportion ot' the edge of the comwhich is nearest to the annular ratchet-wheel. "The type-wheel is inkedby means of a brush, which is mounted on i angles to thc type-'wheelshaft.l i `i i i i i i ,i v A suitable-device is `obtained to' arrestthe type-wheel ata stop, beforerbeginnirig a` sentence.

Foce-platos, bo, are secured to the ends ot" each electro-magnet, as'shown in gs. 1 and 7.

'lhe four face-plates on that pair of electrorriognets which' is cnonefside of' the horse-shoes, are opposite the poles of the borse-shoes,and those on the other pair lare also opposite the poles.

Thus it wiil'be' seen' that when 'the appnrntns is sett in operation,the dingonnllybpposite electro-mignotte will respectively ottrnct andrepel'thehorsefshocs, and thitifns the polarity of tbe electro-magnetsis reversed, the action upoiffthe horseshoes will vberejfersctl', andthnt ths en oscillating motionis "imported to the letter.

By means ot' the screws e, the springs can be merle strong or wenk,'ais'm proprlyndjusted the horse-shoe rngnet will move in the 4centre'ol' the whole force." t

The mngneticcombinntion is thus molde permanent for all kinds of weathernnddegrees of current... To one o f the horseels'hoes isattecherlsil-insulated sleeve,f, which oscillntes with thc horse-shobbtween twoarms'proj'ecting from a. pilleng, as is clearly shown in iig. I' f I Thepillar, as well as the sleevef, is connected, by means of wires, with abattery, and with n local mogmotion-of the borseshoewith the rebound.- t

aybe desire,.nr1l' when they are net, F, asris indicated iny fig. 1. Aslong as the borse-shoe oscillntes, the contact between the sleeve andpillnr-arms will be ofltoo short duration 'to establish a. circuitbetween the 'two wires, but when the motion of the horse-shoe oenses,'by the action upon the keys C, the sleeve will rest agelinst one arm ofthe piller, or against on adjustable stop'nrrangef in the same, and nconnection `between theltwo wires of the local mnhgne't will thus beestnblishetl'whenevez the osoill'ntions of the horse-shoe magnet cease.I i

- The armature F ot' the local niagnetis'drawn down upon itscoils onlywhen n connection between its two wires iV established, d nringth'e restof the horse-shoe magnet.

Armature F of `the local magnet is secured to en armf/z, which projectsfrorn an oscillating horizontal shaft, G, said shaft having a. cran'lrtowhich a. strong spring, t', isnttached, which has tbetendency toraisefthe armature F of the'local magnet as sooniis the connectionbetween its wires is interrupted.

' An arm, j, which projects from Vthe a'xle G, acts ns nu escnpenlcntfor a. toothed wheel, H, whichie mounfilecl on an upright axle,'asshown,`and which has n constnnt tendency to revolve in the direction ofthe arrow ll, figs. 1 und 4, itA being connected with a. revolving belt,c. ns shown. l

the surface of the friction-wheel Hnre set n. number of upright pins, ZZ, asis clenf'rly 'shown in the drawings. i is an oscillating lever,pivoted ncortlie middle to the platform A, ondconnccted at one end witha. sleeve, m, which slides nnd/ tuorns on a. horizontal slinft, J, nsshown in tig.v 1.

From this sleeve m projects radially an arn,11 having e bent-out arm atits outer end. The arm n is in front of an annular disk, L, which hasslots cut into its rini, as shown in g. 2, the num'- ber of such slotsor recesses being equal to that of the keys C. l

The leverI has an arm, '0, which is connectediwitb e. springdo,that'tenrls' to draw the slee-ve m towards the disk L, so as t-o lockthc'projecting arm of the bar n into a recess' of the disk L.

"'iiily'ulicn the back end of the lever I is held b y one of the pins Zof thewheel H, as in fig. 1, will the` bor u be held ont ot' the disk L,as in lig. 1, butn as soon 4s, by the stopping of the horse-shoemagnets, the` lolnlilnialgnetisfdiawndown', so as to raise the escapemen t the wheel H will be turned by its-belt or cord, sind` willthereby release the lever I, which will be acted upon by the 'spring,p,so that the bar n will be locked into the disk, as shown in g. 4.

The wheel H, when it is thus released by theaction of the vlocal magnet,will not turn' far', as it will soon be stopped by anotherescapement-lever, M, attached to and swinging on an upright axle, asshown in fig. 4, inwhich also .the manner of stopping' the wheel H bythis lever M isarep'resentecl.'

Theqcennectiens ofthe lever M will bel hereinafter described.

I The horse-shoe magnets E E are, by means of suitable-levers, q, erdirectly, connected with an oscillating escapement-lever, r, whichengages a toothed wheel, s, that has half as many teeth as there arekeys C.

The wheel s .is mounted o n a sleeve, t, which is tirranged around theshaft J, as is more fully shown in iig. 3.l

The sleeve t carries a disk, u, which is set in an inclined positionupon the sleeve, as vshown iniig. 3, and a forked bar, c, pivoted to anarm, w, that projects from the axle J, straddles the edge of'the camu,as shown in fig. 2.

' pin, e', has been attached to the sleeve t.

i The sleeve t receives its motion from a hair-spring, c, of which theinner end is attached to the sleeve, while the outer end-isV attached toan annular ratchet-wheel, y, which is fastened on a stationary disk,'z,that is secured to the platform,-as shown in fig. 2, the wheel y beingfree to turn around its axis in one direction, and a pawl, a',preventing rotation in the opposite direction, as shown.' Y Atthejunction of the spring z with the ratchet-wheely, projects fromthe faceofthe latter ra blocker pin, lb,`wl1ich can be reachedby the end of anarm, c', which projects from the fork n, as shown in figs. l and 2, whenthe said fork is on that portion ofthe edge ofthe cani u which is nearestto the ratchet-wheel As the shaft J is, by devices to behereinafter described, revolved with great velocity,'it is evident thatthe fork v, which is pivoted to an arm, projecting from the shaft J,willbe carried around the disk et, which is rotated but slowly by theescapement-motion of the Awheel s. Y A

Whenever the end of thespring :c will be unwoimd, or nearly so, the barc will reach the block b', and will turn the ratchet-wheel y, so as towind the spring partly lnp again, and thus thespring will/be constantlyautomatically Wound up as it is being unwound. i -l o l Y The cam u isnot so much inclined as to allowgtheba'rc to be locked for toolonga time.withfthe pin t, so

that the spring cannot be overwoundfbut still, to prevent any possibleoverwiuding ofthe sprin g,a projecting When the :spring Ais quite`vwound ulnthey ratchet-wheel y is then prevented. v Y

pin b strikes against the pin cv', and vthe further turning of the Thesleeves m and t are connected by means of a pin,f,whichlis. attached toone of them, and Ets through a hole in the other.

Thesleeve t can only turn onthe shaft J, but the sleeve fm, can alsoslide on the same. v l

By moans of ,tho rotation which is, by ythe action of the spring a: 'and'by the motion of theescepemen't-lever r, imparted to the wheel s, andconsequently also to sleeve t, andV by means of the constant connectionbetween thc sleeves `t and m, the latter isvalso rotated, andwith'itlits bar n.. l

D uring each move ofthe sleeve t, which is occasioned by its temporaryrelease from one ofthe 4pins ofthe escapement r, the end of the bar willbe moved from one recess te theother 'of the'di'sk L, and during acomplete revolution of the sleeve t, the b ar ln pwill also have made.one complete revolution, and'will stand opposite to the recess inthedisk L from which it started; v. I 7 'f l From the shaft J projects anarm, N, with hook-shaped outerend.'

This arm, when the bar n'. is out of the disk L, fits over the end ofthbar n, and allows the latter to f 'revolve freely, being itself n otdetained,'as indicated in iig. 3. But as Boones, by `the action ofthelocal mag net, as before described, the end ofthe arm'n is thrown intoone of the recesses of the disk L, the said bar n 'willbave been movedinto the Vtrack ofthe arm N the endet' which will strike against the-endof the arma.

Thus, by the locking of the ba'r n into the disk-L, thefurtherrevolutieu of the sleeves 'm andi is stopped,

but also that of the shaft J, 4cwingto the'arm n and -N vcoming incontact with each other while one of them is and m', and ofthe axle J,is stopped.

firmly locked. 4 v Thus, as the horse-shoe magnet ceases to move, by theaction upon Vthe keys, the rotation of. the'sleeves t Between everytwosu'ch stoppageathe bar n moves across an equal number of recesses o fthe disk L as the horse-shoe has made oscillations; andthe number `efthe latter were equal to the number vof keys between thetwo'last-touched keys. v v v I I j."

The shaft J carries the type-wheel O, on the'periphery of whichtherequired types-are arrangnfedl The numberof types is' equal to thatof recesses in the disk L, and equal to the nnlniberh'of keys and4double the number `of teeth o'n the .wheel s. v v

Freni one face of the type-wheel O projectpins, g-, one opposite toev/ofy type, as shicivhn'indigs.l llA and 4. The shaft J receives itsrotary motion by means lof a4cam, lP, which strikes againstpa `pin, IL',that projects.

from the face ofthe type-wheel, as shown. l I L lThecaurP is pivoted toa pin thatprojeets yradially from a shaft, R, which shaft is acontinuation of thc shaft J, but notpart of the same, as shown, l I.

At the same time,- the arm willfbewithdrawn from the edge of the type-wheel, as shown in iig. l, and thearm M will rest upon the faoe ofthewheel H, so as to hold a pinyl,between its forked arms without detaining it, as shown, so that thewheel H may revolve if released bythe eseapementj. As scones, by theaction of the arms fn. and N, thefurther revolution `of the type-wheelshaft J is stopped, the sanft R will continue to revolve, and the cam lwill then be brought withfsueh force against the then stationary pin 7Lthat the power of ,the spring vit/will be overcome,

By this motion of the sleeve, the end of the arm T will be moved baolctoo,'and thereby-,the arm TJ will he 4.nfifovecl-against the edgeof thetype-\.vheel, bringing its Wedge Z between twoof thefpin/s-gf on thesame.4

To the pin Sis also pivoted an arm, V, which carries a cushion in oneface, and which, when the pin S is turned bythe stopping of thetypeert-heel, is, by means of 'a strong spring,vo, which is firmlysecured to a pin projecting from the arm U,pressediagainst the edge ofthe type-wheel. e

,1 y By ltheaforesaid rotation of the cushion-armi?, the paper ispressed by the said arm against that type on .theevvlieelwhichis'ofpposite tothe cushion, andwthus receives the required imprint.

Torecapitulate the operation of the machine, it should be borne in mindthat the oscillations of the horseshoemagnet between every action of thekeys C are equal in number to the number of keys that are between thetwo "last-touched keys.

`Lehigh.titty vr-While the borse-shoe osciliates, the arm n traverses anequal number of recesses on the ldisk L as there aremovesmade by thehorse-shoe, and when V'the horse-shoe stops the arm stops also, and islocked into that distant from the same as there have beenoscillations-made by the horse-shoe. Y

Then-the arm N- arrests the motion of the type-wheel shaft, and locksthe Asame in a positionwhich brings the `required `type in front of theprintin,1g-cushion.` ,1" i v v i Therelative positionof the type-wheelis, (as it is stopped by the arm n, the motion of'whichiis regulateth)such, thatthe'same number of types will be 'distant between the typelast printedand that, to be printed, as there areikeys between theftwekeys last touched. l Y Y l Whep thefrictionavheel H is by the action ofthe' local magnetzreleased, itturns and releases thelever the spring@moved so as to lock the bar n intothe disk .T .1'

The furthbr revolution of the wheel H is stopped by the forked arm M,one of the ends of which receives a pin, Z, asshown' in g. 2.

While, then, the type-wheel is stopped in the manner described, and thepaper is being printed, the arm Mjis moved in themanner set foi-th, andreleases its pin Z, so that the wheel H may be turned until'it is againarrested by the lever j. v

By this turn-oi` the wheel H, the lever I is again moved so as torelease the arm n from the disk 11n/thus allowing the further revolutionof the type-wheel shaft, and the paper is at the same time also fedfurther ahead to take the printed portion of the type-wheel, and thus,by this slight motion of the arm M, the lwhole apparatus is again setfor'further operation. l,

As soon as the type-ivheel shaft Tis again free to revolve, the camP'will assume the original position, and will revolve the shaftas theVsleeve a" will be moved Yby `the arm T towards the type-wheel, so as tobring the cam P against the side of the pin L, as shown in iig. 1.

The same is mounted o n a horizontal shaft, which stands at right anglesto thc type-wheel shaft.L

The brush will `be revolved by the typewheel, and, by supplying thebrush with a small .quantity ot' ink, the same' will be rapidly spreadal1 overr the brush, owing to the rapidity with which it revolves, andwill keep one of; therecesses -which is' as far from the recesses Aintowhich it was locked before, or rather as many recesses the typesuniformly blacked, besides keeping the letters free from gumming up.

Tlie wedge l', on tho arm4 U, serves', besides being a. support for thepaper, as a means to prevent the type wheelfrom turning back during theprinting pperation.
